Building extension in system construction
At the Rudolfstetten site, an existing warehouse building was expanded by adding more than 1,000 m² of more than 1,000 m². A hybrid construction consisting of classic steel construction, Sigma profiles and a lightweight steel construction system was used.
Swiss pioneering project in steel and drywall construction
The combination of steel construction, lightweight steel construction and gypsum drywall systems in this form represents a Swiss premiere. The high degree of prefabrication of the elements enabled rapid construction progress: exterior wall elements were delivered fully planked and could be assembled directly.
A key advantage of the chosen construction method is the low load input compared to conventional solid constructions. As a result, no additional reinforcements of the existing supporting structure were required – a decisive factor when adding storeys to existing buildings. At the same time, the relevant building physics requirements such as earthquake safety, snow loads and wind pressure were met.
System integration and flexible internal structure
The interiors were structured with lightweight steel construction and gypsum drywall systems and supplemented by acoustic ceilings. The cross-system interaction enabled a flexible room layout as well as an efficient implementation of the work and usage areas.
Relevance for dry and system construction
The project shows the potential of modern lightweight steel construction and drywall construction systems today. A complete building extension without concrete and brick, with a few classic steel construction elements and a high proportion of prefabricated systems, opens up new perspectives for system construction.
The possibility of implementing such additional storey projects largely independently is particularly relevant for plasterers and drywall construction companies. Prefabricated elements, clear assembly concepts and technical support during the project make a significant contribution to the reliability of execution.
